Raspberry PI - Installing Python Binding for INDI was created by Mathieu Corbett

I've been attempting to install the Python binding for INDI on my Raspberry Pi 3, following the instructions here: indilib.org/develop/tutorials/151-time-l...ith-indi-python.html . When I get to using the make command, I keep getting the same error (below):

I've managed to fix this by copying libindiserver.h and fq.h out of the libindiserver directory in swig-indi-python. This gets rid of the above error, but generates a new one:

Hi Mathieu,
The link you have used is no longer valid, it is still there for testing purpose.
The pyindi-client should be moved to pypi, for the moment I only put it on testpypi .
You may follow the download method (and then simply run python setup.py install) or try the pip way (I did not test it yet) specifying the testpyipi index site on the command line

pip install -i https://testpypi.python.org/pypi pyindi-client

Your logs show that compilation of the client is error free (only warnings) and that the above installation should succeed if my pypi setup is correct. May you confirm that last point ?
Thanks,
Jean-Luc.

Hi Jean-Luc,

I actually stumbled on the pypi alternative shortly after posting this. I haven't had the chance to try it out yet, so I'll keep you posted.

Thanks,

Mathieu

Edit:

Installing through pip doesn't appear to have worked:

Hi Mathieu,
I just tested the pip method on a rpi2/archlinux and that worked.
Now I have forked and cloned the new indilib repo on github and recompiled all the stuff on my desktop. As this is a 64bit architecture, every libindi libs are now put in the /usr/lib64 directory.
So you may change the extra_objects field in the setup.py file before running it.
I will manage to change that on the pyindi-client repo and test again.

Jean-Luc.

Hi Jean-Luc,

Thank you for taking the time to do this.

What should I change the extra_objects field to? Also, Raspbian on the RPi does not have a lib64 folder, unless I'm looking in the wrong place

Have you tried with

dpkg -L libindi
dpkg -L libindidev

here you should find the libindiclient.a file, and its installation directory. Debian uses lib/<multiarch-tuple> directory names.
You may also try with locate

locate libindiclient.a
